Specification of Letters Patent.

Application filed June 4, 1910.

To (LZZ whom it may concern:

Be it known that I, CHARLES KUEHNER, a citizen of the United States,residing at the city of Providence, in the county of Providence andState of Rhode Island, have in vented certain new and usefulImprovements in Pins, of which the following is a specification,reference being had therein to the accompanying drawing.

This invention relates to a pin, and has for its object to provide acombined pin and setting for an ornamental stone or the like, whichcomprises a body portion having means for securing the ornamentationtherein, and also having both the joint member and the catch member forthe pinstem formed integral with said body portion, and stamped fromstock within the outer periphery thereof.

With these and other objects in View, the invention consists of certainnovel features of construction, as will be more fully described andparticularly pointed out in the appended claims.

In the accompanying drawings: Figure 1 is a side elevation of thecomplete setting. Fig. 2 is a central longitudinal section with theornamentation removed and showing the construction and arrangement ofthe joint and catch members. Fig. 3 is a top view showing the shape ofthe catch member and of the joint member as they are cut from the bottomof the cup-shaped body. Fig. 4 is an enlarged side elevation of aportion of the body showing the joint member bent up into shape. Fig. 5-is a section on line 55 of Fig. 2 looking in the direction of the arrow,showing the free end of the joint member engaging the flange of the bodyportion. Fig. 6 is a perspective view of the pin tongue and head.

Referring to the drawings, 1 designates the body portion of the pinwhich is preferably formed from a piece of sheet stock being firststruck up into a cup-shape to form a setting. The edge of this cup maybe provided with prongs 2 or projections, for the purpose of engagingand retaining the ornamentation 3, or the upper edge of this bodyportion may be made plain and drawn down thin to form a box setting, ifdesired. After the cup is formed from the blank the bottom portionthereof is punched or cut out leaving a blank catch member 4 and a blankjoint member 5 integral with said body, and also forming a narrowinturned flange or shelf 6 extending around on either side be tweenthese two members. The catch member 4 may then be bent outward, asillustrated in Fig. 2, the end 4 being bent at right angles to the shankportion 5 with its edges 7-7 curved slightly upward to form a slightgroove to receive and retain the pointed end of the pin stem.

The joint member is formed with a comparatively narrow neck 8 having aT-shaped head portion 9, said head being provided with recesses 1010 oneither edge. The stock forming this narrow neck port-ion is providedwith an elongated hole 11 for the purpose of receiving the stem of thepintongue. In forming the joint from this member the narrow portion 8 isbent or forced outward from the plane of the flange 6 into substantiallya U-shaped loop, the pin stem hole 11 being in one wall thereof and inposition to receive the pin stem therethrough. As this narrowed portionis bent outward into the loop form the T-head 9 is naturally broughtback into the position illustrated in Fig. 4, the flange 6 engaging andfitting tightly in the slots 1010 on either side of said head, see Fig.5, thereby holding this free end of the joint firm and rigid against thestrain of the pin stem which has its fulcrum bearing therein. Thepin-tongue 13 used in the joint member is preferably of the type havinga T-shaped head 14, and when placed in position the stem extends throughthe hole 11 and the head lies in the bottom of the loop. The walls ofthe stock are then drawn or forced together forming a strong jointintegral with the body portion of the setting. The pin stem works in theslotted hole through the wall of the joint member. By this constructionwhen it is desired to carry the jointed end of the stem into the catchmemvice as a whole is strong and economical in cost. This is due to thefact that the continuous flange 6 which projects inwardly from the sidewalls 1 of the body, strengthens the body so that its upper edge isadapted to firmly hold an ornamental member such as shown at 8, portionsof the same flange being extended and bent to form the joint and catchmembers.

The joint and catch members of a onepiece pin are usually stamped fromthe stock and formed on the outside of the general outline of the bodyof the pin, but by my improved construction it will be noted that boththe joint and catch members are formed integral with the body portionfrom the stock within the outer periphery of the pin body, thusutilizing stock which would otherwise be wasted.

Having thus described my invention, what I claim is:

1. A pin comprising a cup-shaped body portion the bottom of which isformed With 1 an opening leaving a continuous flange proectlng inwardlyfrom the side walls, portlons of sa1d flange havmg integral pro ectionsforming joint and catch members, the I joint member being interlockedwith said flange.

2. A pin comprising abody portion having an inwardly projecting flange,portions of said flange having integral projections forming joint andcatch members, one of said members having edge recesses engaging saidflange.

3. A jewelry component comprising a body portion having an openingwithin its margin and provided with a joint member formed integraltherewith from the stock Within the general outline of the body portion,saidjoint member comprising a tongue integral at one end with the bodyportion and bent outward to form a loop to receive the head of apin-tongue, the other end of said tongue which forms the joint memberhaving its edges secured to the margin of the opening in the bodyportion.

In testimony whereof I afiiX my signature in presence of two witnesses.

CHARLES KUEHNER.
